Bait known that i, H ENRY lI. SANDZGLL. a citizen of the United States,residing at Chicago, in the county of Cool: and State of illinois, haveinvented ano r and useful improve ment in Sheet-Perforating Machines, ofwhich the following is a specification.

My invention relates more especially to an improvement in the class ofperforatingmachines for producing the music-sheets employed inself-playing instruments. It may, however, be used for perforatingsheets for other purposes.

The primary object of my invention to provide a construction of machinein the class referred to which shall be devoid of any lever-operated orjointed parts, and accordingly comparatively simpleand durable, with theminimum liability to get out of order.

The motive power which is preferred for controlling the operation of myimproved perforatirig-machine is electricity, although pneumatic orother motive power may be used for releasing the spring-driven punchesfrom their normally inactive position, and as the machine has beenespecially designed for perforating paper sheets for use with theelectric self-playing violin forming the sub ject of my application forLetters Patent, Serial No. 252,228, filed March 27, 1905, l employ inconnection with the machine for pro ducing the perforated sheetssubstantially the same electrical contact mechanism to be traversed bythe master-sheet and driving mechanism for the latter as are employed inthe aforesaid violin-machine to produce playing ofthe instrument. Theselast-named mechanisms and their connection with the perforating-machineare illustrated as representing one embodiment of my invention in theaccompanying drawings, :of which the following is a description.

Figure l is a view in side elevation of the entire machine, except themotor for driving it, which is OlDlttGCl for lack of space on the sheetand because it is unnecessary to represent. Fig. 2 is a. plan view ofthe perforating-machine proper with all the magnets but one deenergizedand the parts they control in corresponding condition. Fig. 3 is anenlarged section taken at the line 3 on Fig. 2 and viewed in thedirection of the arrow. Rig. 4 is an enlarged lH'OlUZH view, insectional-i elevation, showing a punch in its raised position and thespring-advanced and magnet-retracted means for holding the punches intheir inactive raised positions to which they are forced by a rotatingcainagainst the springs which tend to depress them; and Fig. 5 is asimilarview of the same, but showing a punch in its depressed position.6 is a view in elevation of the feeding and contact inechan isms for themaster-sheet. Fig. 7 is an enlarged plan section taken be line? on Fig.3, showing in plan the entire seriesof notched arrester-shoes carried bythe punches. Fig. 8 is an enlarged View, in cross-sectional ele=vation', of the feeding and contact mechanisms for the master-sheet.Fig. 9. is a broken perspective view showing one of the arms-terequippedpunches presenting the locking notch in one side of the arresteig andFig. 10

is a similar view of one of the same deviceswhich presents thelocking-notclnon the opposite side of the arrester. Fig. 11 is a diagramillustrating the generator circuits in which the mechanisms forarresting and releasing the punches arecontained.

The generally-described operation of the electrically actuated pertatingmachine illustrated is the following: A master-sheet is fed across a setof contacts, each having in circuit with it an electromagnet, and asheet to be perforated is fed correspondinglywith the master-sheetacross a row of reciprocable punches, each normally held away from theWork against the tension of a spring which drives it,'the punches beingreciprocated by a cam actuating them in one direction and theirdriving-springs actuating them in the contrary direction. As aperforation in the traveling master-sheet registers with a contact thelatter closesa circuit containing the respective e'lectromagnet toattract its armature, and thereby release the punch, which is normallyheld out of action by the springpressed armature of the magnet in thedeepergizedcondition of the latter. Upon such release of the punch arapidly-rotating cam coacts with the punch-driving spring to reciprocate the punch rapidly, and thus cause it a perforationcorresponding with that through which the circuit closure occurred.

,to cut in the travel ng sheet to he perforated near one end. issupported feeding and con tact mechanism 3 for a master-sheet (I, whichmoves across an inclined guide-board a and thence between a feed-rollerand a contactroller 0, with which latter a series ofspringcontact-teeth7 are supported to engage through the perforations in the master-sheetas they i the under side of the table A, is immovably secured inhorizontal position a fulcrum-rod c.

On tlierighnhand end of this rod is journaleda grooved pulleyf, from thecenter of one face of which projects a pinion f, Fig. 6. On the same endof the rod (2 adjacent to the hearing is journaled a hanger g, and nearthe opposite end thereof is journaled at its hub or sleeve a similarhanger g to depend at the inner side of the bearing-plate c, said hubprojecting through the plate a and carrying a crank-handle g in thelower ends of the swinging hangers g and is journaled the feed-roller7), which may be composed of hard rubber and which carries on one end aratchet wheel f meshing with the pinionf, and the feed-roller cooperateswith the, metal coptactroller 1;, journaled in the bearing-plates e e tofeed a sheet C by clamping it between the two rollers, which areseparable for arresting the feed for any purpose by manipulating thehandle g to swing the hangers. Spring-rods,

each like that shown at h in Fig. 8,are supported in engagement with theswinging hangers above their fulcrumpoints to give to the lower ends ofthe hangers a tendency to turn toward the contact-roller and to thefeed- The details thus described are substantially like those of thecontact and music-sheet-feeding mechanisms shown and described in myaforesaid pending application. However, any other suitable feedingmechanism may without departure from the'invention be employed vith thesheet-cutting mechanism hereinafterdefscribed.

' The pulley f has a belt connection f 'with a smaller pulley 71' on acounter-shaft i, journaied in bearings depending from the table A andcarrying a larger pulley 2'1 which has a belt connection vi" with apulley y" on'a camshaft j, journaled in suitable end hearings on aframe 1) upon the upper side of the supporting-table, the cam -shaftcarrying a large drivepulley 1;, connected by a belt k with the drivingpower, (not shown,) such as an electric.

motor. The pulley j is preferably of the differential-speed variety, asshown in Fig. 2, for

' subserving the purpose hereinafter explained.

The sheet-cutting mechanism involves ahorizontal row, extending acrossthe center of the frame D, of vertically-reciprocating punches E, ofwhich any desired number may be provided, though for my immediateaforesaid purpose of providing perforated sheets for the saidautoniatid'violin-playing machine fifty-eight are provided, being-twelvefor the chromatically-operative lingering devices for achstring of theinstrument, one for each open string, four for the magnets controllingthe pressure of the sounders on the strings, one for the tremoloattachment, and one for controlling the starting and stop page of themotor which operates the violin-playing mechanism. The punches workthrough openings, one for each punch, in a bar F, extending across andsupported in the frame .D and having fastened to its respective sidesplates F and F which project below the lower face of the punch-bar andare provided near their lower edges with horizontal series ofguideopenings Z for a purpose hereinafter described, the members of oneseries being in staggered relation to those in the other series. Eachpunch has a coiled driving-springE confined against its upper end in therespective vertical punchcontaining opening in the bar F by atension-adjusting screw E these screws working in threaded openings in abar F supported on the frame to extend over and parallel with the bar F.Underneath the punchbar and coincident therewith is supported on theframe 1) a pair of parallel die-bars G and (51, having coincidentvertical punclropenings m and in. extending, respectively, through themand with which the punches coincide, each opening m. leading to a largeropening m in the bottom part of the frame through which to discharge thematerial cut by the punches out of the sheet being perforated, ashereinafter described, and for the passage of which latter through theperforating-machine portion and a bearing-insert 12., preferably ofvulcanized fiber, in the sole of its foot portion to'be engaged by thecam-shaftj. The notches It are provided successively 1n oppo- "sitesides-of the arresters throughout the series thereof for-the purposehereinafter described. The arresters thus form, practically,

parts of the punches and are guided by their reduced or too ends a",entering vertical slots of in a guide-plate n", extending across theframe.

In the frame I), on each of two sides thereof, are supported to projecttoward itslongitudinal center an upper set anda lower set ofelectromagnets K, each having its armature reciprocably supported in apole extension 0 andprovided with a linger p, projecting from it towardthe center of the frame and suitably bent to register its taperedextremity, which works in a guide-opening in a bar F or F as the casemay be, with the plane of a notch R in the respective shoe 1 when thepunch-carrying that shoe is in its normally raised position. Thus thefingers p of the magnets on opposite sides of the frame D arev adaptedto orig; "e the notches in the arresters,

respveti'i ely, presented to them. Each finger,-

The number of the magnetscorresponds w th that of the contacts (Z,iifteen being provided in each upper row and fourteen in each lower row,and each magnet is connected c represented in the diagrammatic f gs w ofthe l ings, by a separate conductor w with a uiuerent contact (Z, andall thecontacts cooperate with the roller which is connected by aconductor 2 with the positive end of an electri -current enerator.indicated at L.) the negative end having connected with it a return-condactor-1E with which all the magnets 'LI'Q- connechcl. as indicated inthe diagram.

The material to he perforated may be provided in the form of a roll ofpaper M, Fig. i, from which to pay on by the action-of the feelingdevice on the perforating-machine. 1h.- roll being journaled instandards, one of which is represented at M, supported on the ta le A,and the end of the sheet being carried across the pin dies through thespace H and gripped between feed-rollersll'and G. 'lhese rollers arejournaled in standards on llaftable A, one of which standards isrepresented at N, the roller l, carrying a ratchetu'ieel r, engaged fordriving it with an intern zitent motion by a pawl r operatively con- 3 5nected with one end of a pitmau rod r having a i; rank connection at itsopposite end with the earn-shaft j. lliis connection is represented 1.7a slotted bar P let into the end of the shaft (see Fig. and straddling aheaded stud s c 4o centrically mounted on the end of the shaft an l onwhich the bar is ad ustable to inc-r e or diminish the extent of strokeof the pits man connected with said bar and according, y vary the extentmovement of the pawl v" to adapt it vary the feed accordingly. A stillspring 5' is shown in i ig. 1 bearing periphery of a pulley Z on theagainst the snaft which carries the reiler N to act as crate to preventthe sheet undeigoing perfo- 5o ration from turning by its tension thefeedrollers N and O baclnvard in the intermission between the turningengagements of the pawl o" with the ratchet r.

The operation is as foil-o s: With the sheet to be perforated grippedbetween the rollers for feeding it and the master-sheet *Q adgiustedbetween the rollers i) and c the driving power is caused to turn thepulley if, and with it the III-Shaft 7'. thereby driving from the latterre teed mechan I 1 :sheet and. that of the sheet to he perfoln thenormal condition of the machine while rest all of the punches are abovethe path of the sheet to be perfo 5 being release y loclced in the forthe perforated masgazed.

Closure of the'circuitenergizes the respective'magnet to attract its armature, with the etfectof retracting the linger 1 it carries from engagement with therespective arrester 1, thereby releasing the particular punch controlledby that arrester and permitting its driving-spring E to force it throughthe space H and puncture thesheet M accordingly. ln each revolution ofthe rapidlyrotating cam-shaft j by its engagement with the respectivepunch at its arr-ester portion l at the insert 2?. it raises the punch,and inthe Q0 punch, while in the interim between the cutting. andreceding movements of the punch the rotatory shaft 7' actuates the pawl.1" to feed the paper. The adjustment of the parts is such that-in thetravel of the sheet M the perforating movements against it of a recip-.rocating punch occur at intervals of about three sixty-fourths of aninch, thereby causing the successive perforations to overlap one.another to form the elongated openings in the paper. Of course, howeverthese intervals on the paper being perforated may lie-varied to anydesired extent. The moment that the perforation in the master-sheetpasses the respective contact, with thc result of opening the circuit byinterposing paper between the contact and the roller 0, thespring-pressed linger p of that magnet shoots into the path of thearrester .l to engage its notch n in the rise of the punch un'der thecam-shaft action and retain the punch out of operation until the magnetwhich controls it is again ener- The foregoing description of theoperation of one punch will suflicefor all. From it will readily beunderstood by those skilled in the art that each perforation in themastersheet is reproduced in the sheet undergoing perforation by thereciprocating action of the spring-driven and cam-retracted. punchesthey are released from their normally withheld ccndition to permit themto he reciprocd through the sheet in its stoppages while it being fedacross them.

The differential driv -pu1lcy serves as a "ea ly means for lowering andraising at will i of feeding the master-roll whi sult of increasing thetempo in its playing action. The present invention is primarilycharacterized by driving the punches through the' sheet materialundergoing perforation with springs and retracting them to produce theirlongitudinal reciprocation relative to the sheet material through themedium of the retatory cam-shaft or other means positively actingagainst the punches in opposition to their d rivingsprin gs. Thisconstruction'pre sents the important advantage as against raising thepunches by spring action and driving them by cam or lever mechanism inassuring the instantaneous driving action of each punch when releasedand its positive re traction from the path of the sheet iii-eachreciprocating stroke, whereby tearing ofthe intermittently travelingsheet by 11mm rate or untimely Withdrawal of the punch is avoided.Moreover, this principle of operation enables the construction to besimple and durable Without liability to disarrangemeiitof parts, sincethey contain no jointed members, and the only elements of the mechanismwhich ever require attention after the machine is once in Working orderare thepunches, which require to be sharpened occasionally.
